The thing I've run across is that people who haven't followed this as closely are still stuck back in March and who will think of him as "That Duke Kid Who Got Away With Rape".
I'm sure someone in the media will reveal that the students have enrolled at other colleges. They still have a fine chance at becoming anonymous if they choose to.
Still, I'd get the flashy Ferrari if it were me as long as someone else was paying for it. I'd also let it be known on campus that if I caught anyone spreading malicious information about me regarding the Duke case, my lawyers would get involved.
